The FindZip macOS ransomware was spotted last month by researchers at ESET, it is tracked as OSX/Filecoder. The first release was not complete, the victims were not able to recover their files, even if they pay the ransom. The process has been automated later by experts from Avast who developed the FindZip decryption tool. Victims can decrypt their files on either a Mac or a Windows machine by using the tool. The tool was successfully tested on Mac 10.10 (Yosemite) and 10.12 (Sierra)”]
